The Chauvin Arnoux CA 5011 is an analog/digital multimeter designed for precise measurement of electrical quantities in industrial and craft applications. It combines a digital display with 4000 digits for high measurement accuracy and an analog scale for quick visual reading and trend detection. The device is designed as a TRMS multimeter, meaning it displays the true RMS value of voltages and currents, regardless of whether the signal is sinusoidal or distorted. This makes it particularly suitable for installations with non-linear loads, such as those found in modern electronic devices or power electronics.

Applications
This multimeter is intended for use in electrical installations up to category CAT III 600 V according to IEC/EN 61010-1 edition 2. It is therefore suitable for measurements in industrial, commercial, and residential electrical installations where high safety requirements apply. Electrical safety is certified to IEC 61010-1 edition 2 600 V CAT IV, ensuring a high level of protection for the user. The operating temperature ranges from -10 °C to +55 °C at a relative humidity below 90 %, enabling use in various environments.

Functions and Equipment in Detail
The device features automatic AC/DC detection, enabling measurement of direct and alternating voltages and currents without manual selection of the measurement type. Voltage measurement covers five ranges from 400 mV to 600 V, with typical accuracy of 1 % for direct voltage and resistance measurement. The input impedance is 10 MΩ, ensuring high load independence of the measurement. Current measurement covers six ranges from 400 µA to 10 A, with accuracy of 1.5 %. Resistance measurement is available in six ranges from 400 Ω to 40 MΩ. Additionally, the device offers an audible continuity test with a threshold below 400 Ω, which is helpful when testing wires or contacts.

Technology Explained Simply
The TRMS technology enables accurate measurement of RMS values even for non-sinusoidal signals, which is critical for modern electronic devices with pulsating or distorted current waveforms. The digital display with 4000 digits ensures high resolution, while the analog scale allows for quick visual assessment, for example, in detecting fluctuations or trends. The maximum value function stores the highest measured value over a period of over 500 ms, which is useful for analyzing transient voltage or current peaks. The backlight facilitates reading in poorly lit environments.

Compatibility and Accessories
Various accessories are available to extend functionality, including test leads with 4 mm connectors in different configurations (straight, angled), test probes, crocodile clips (alligator clips), and fuses rated at 1 A and 10 A. These components are designed for use with CAT IV 1000 V or CAT III 1000 V and enable safe and flexible measurement. Transport cases and bags are also available to ensure safe transportation of the device.

Mounting and Installation
The multimeter is compact and portable, with dimensions of 160 x 105 x 56 mm and a weight of 500 g. It features a shock-resistant housing and a foldable stand bracket that allows stable placement on a flat surface. Power supply is via a 9-V battery (type 6LR61), enabling up to 300 hours of operation. The fuses for current measurement ranges are HPC fuses rated at 1 A and 10 A and can be replaced if necessary.

Operational Advantages
The combination of digital and analog display offers an optimal balance between precision and quick visual assessment. The TRMS function ensures reliable readings even with complex signals. The integrated Voltest" indicator signals the presence of stray voltages during resistance measurement and continuity testing, enhancing safety. The "Fus indicator light informs about the condition of the fuses, which is helpful during troubleshooting. The device can also be used as a null point galvanometer, which is useful in specific applications. The IP53 protection rating protects against dust and splashing water, enabling use in outdoor or damp environments.

Protection Rating and Environmental Conditions
The IP53 protection rating ensures the device is protected against dust and splashing water, allowing use in industrial or outdoor environments. The operating temperature range of -10 °C to +55 °C and relative humidity below 90 % extend the application range to various climatic conditions. Power supply is via a 9-V battery (6LR61), enabling 300 hours of operation. The fuses for current measurement ranges are HPC fuses rated at 1 A and 10 A and can be replaced if necessary.

Additional Functions
The multimeter features a dB scale for AC voltage measurements in the range of -20 dB to +16 dB, which is useful for analyzing signal levels in communication or audio systems. The Max and Hold functions allow storage and display of the maximum measured value, which is helpful for monitoring voltage or current peaks. The backlight facilitates reading in dark environments. The device can also be used as a null point galvanometer, which is advantageous in specific applications such as calibration or precise current measurement.
